What is the measure of RSQ?

Enter your answer in the box.

Answers

I assume you are looking for arc RSQ, since you already now the angle RSQ.
Arc RSQ is 312 degrees.

Since you know angle RSQ, the arc that it creates is twice the angle.
24 x 2 = 48

Arc RSQ is the entire circle (360 degrees) except for that 48 degrees.
360 - 48 = 312

What are the zeros of the polynomial function?
f(x)=x^2−16x+48
Enter your answers in the boxes.
The zeros of f(x) are ( ) and ( ).

Answers

the zeros would be the 2 numbers when added would = 16 and when multiplied would = 48
 the zeros are 12 and 4

Final answer:

The zeros of the polynomial function f(x) are (12) and (4).

Explanation:

The zeros of the polynomial function f(x) = [tex]x^2[/tex] - 16x + 48 can be found by factoring the quadratic equation or using the quadratic formula. To factor, we look for two numbers that multiply to give the constant term (48) and add to give the coefficient of the middle term (-16). After finding such numbers, the polynomial can be factored into two binomials.

In this case, the two numbers are -12 and -4 because (-12) * (-4) = 48 and (-12) + (-4) = -16. Therefore, the factored form of the polynomial is (x - 12)(x - 4).

To find the zeros, we set each factor equal to zero:

x - 12 = 0 ⇒ x = 12

x - 4 = 0 ⇒ x = 4

Hence, the zeros of the polynomial function f(x) are (12) and (4).

Write log4 14 as a logarithm of base 3.

1) (log4)3/(log14)3
2) (log14)3/(log4)3
3) (log3)4/(log3)14
4) (log3)14/(log3)4,

Answers

The change-of-base formula for logarithms is:
loga (b) = [logc (b)] / [logc (a)]

where:
a = original base
b = original argument
c = new base

Hence,
log4 (14) = log3 (14) / log3 (4)

Therefore the correct answer is D.

Final answer:

To convert log4 14 to a logarithm of base 3, you can use the change of base formula. The required conversion would be log3 14 divided by log3 4.

Explanation:

To write log4 14 as a logarithm of base 3, we would use the change of base formula. The change of base formula is logba = logca / logcb, where logba is the logarithm we want to convert, c is the new base, a is the number, and b is the original base. So, in this case, we want to write log4 14 as a logarithm of base 3, so using the formula, it would be (log3 14) / (log3 4).

The given measurements may or may not determine a triangle. If not, then state that no triangle is formed. If a triangle is formed, then use the Law of Sines to solve the triangle, if it is possible, or state that the Law of Sines cannot be used. B = 137°, c = 6, b = 11

Answers

If you're going to use technology (Brainly), you may as well use appropriate technology (a triangle solver). Many graphing calculators have this function built in.

a ≈ 5.82
A ≈ 21.2°
C ≈ 21.8°

Since the longest side (b) is opposite the given angle (B), the triangle has one solution.
.. C = arcsin(6/11*sin(137°))
.. A = 180° -137° -C
.. a = sin(A)*11/sin(137°)
Final answer:

The measurements given can form a triangle, and to solve it, we would use the Law of Sines. After confirming the possibility of a triangle, we solve for the unknown angle C using the known values and compute the remaining angle and side.

Explanation:

To determine if a triangle is formed by the given measurements and solve it using the Law of Sines, we need to check if the given angle and sides satisfy the triangle inequality. The measurements given are angle B = 137°, side c = 6, and side b = 11. A triangle is possible if the sum of the two smallest sides is greater than the length of the longest side. Here the angle is very large, suggesting that the opposite side (b) must be the longest; however, since side b is indeed longer than side c, this condition is satisfied, so a triangle can be formed.

To solve the triangle using the Law of Sines, we set up the following ratio:

    b/sin(B) = c/sin(C)

After substituting the known values into the equation, we get:

    11/sin(137°) = 6/sin(C)

Now, we solve for sin(C) to find the angle C, and subsequently use the sum of angles in a triangle (180°) to find the remaining angle A. Once angle A is known, we can use the Law of Sines again to find the remaining side a. If at any point we find that the calculation results in an invalid sine value (greater than 1 or less than -1), we must then state that no real solution exists.

It is important to note that if we find angle C to be obtuse (greater than 90°), the triangle will not have a unique solution because it would contradict our initial assumption that angle B, being the largest given angle, is opposite the longest side.

A photograph measures 12 inches wide by 20 inches long. If the picture is reduced so that the length is 8 inches. What is the new width?

Answers

8÷20=0.4
0.4×12=4.8
The width is 4.8 inches

To find the new width of a photograph after reducing its length to 8 inches, while maintaining the original aspect ratio, set up a proportion based on the original dimensions and solve for the new width, which results in 4.8 inches.

The question involves a proportional reduction of a photograph's dimensions. To determine the new width, we need to maintain the same ratio between the width and the length as in the original photograph. Initially, the photograph measures 12 inches wide by 20 inches long. If reduced so that the length is 8 inches, the width will also reduce in the same ratio.

Let's denote the new width as w. The original ratio is 12/20, which should be equal to the new ratio w/8.

Now, creating a proportion, we have:

12/20 = w/8

By cross-multiplying, we get:

20 × w = 12 × 8

w = (12 × 8) / 20

w = 96 / 20

w = 4.8

Therefore, the new width of the photograph is 4.8 inches.

Answers

.. all real numbers greater than or equal to -2 . . . . the last selection
Final answer:

The range of the function f(x) = |x - 1| - 2 is all real numbers greater than or equal to -2.

Explanation:

The function f(x) = |x - 1| - 2 represents the absolute value of x minus 1, subtracted by 2.

The range of the function can be determined by finding the minimum and maximum values it can take.

Since the absolute value of a number is always greater than or equal to zero, the lowest value that f(x) can take is when |x - 1| = 0, which happens when x = 1.

Therefore, the minimum value of f(x) is -2.

As x increases or decreases from 1, the value of f(x) increases.

So, there is no upper bound for the range of f(x).

Therefore, the range of the function is all real numbers greater than or equal to -2.

What is the measure of the missing angle in the figure below?

A. 82
B. 81
C. 80
D. 79

Answers

it is b even though you posted this 2 days ago

Answer:  The correct option is (B) 81°.

Step-by-step explanation:  We are given to find the measure of the missing angle of the quadrilateral shown in the figure.

The measures of three angles of the quadrilateral are 65°, 78° and 136°.

To find the value of x, the measure of the fourth angle.

We know that

the sum of the measures of four angles of a quadrilateral is 360°. so, we must have

[tex]65^\circ+78^\circ+136^\circ+x=360^\circ\\\\\Rightarrow 279^\circ+x=360^\circ\\\\\Rightarrow x=360^\circ-279^\circ\\\\\Rightarrow x=81^\circ.[/tex]

Thus, the measure of the missing angle is 81°.

Option (B) is CORRECT.

Which of the following expressions shows the number of 8 character passwords that can be formed using letters and digits if the password must begin with a letter?

Answers

Answer: 26 x 36 x 36 x 36 x 36 x 36 x 36 x 36 
You may also see it written as 26 x (36)^7

To understand this expression, you must first know that they are 26 letters and 10 digits (1 through 9 and zero).

Now, to find the total number of possibilities, you simply multiply all of the options for each position in the password.

First, we must have a letter, so there are 26 options. Then, for the remaining 7 places, there are 36 options (26 letters and 10 digits).

The expression is 26x36 to the 7th power if the number of 8-character passwords.
